Freshwater salinisation: a research agenda for a saltier world

Trends in Ecology & Evolution, Journal Year: 2022, Volume and Issue: 37(5), P. 440 - 453

Published: Jan. 18, 2022

The widespread salinisation of freshwater ecosystems poses a major threat to the biodiversity, functioning, and services that they provide. Human activities promote through multiple drivers (e.g., agriculture, resource extraction, urbanisation) are amplified by climate change. Due its complexity, we still far from fully understanding ecological evolutionary consequences salinisation. Here, assess current research gaps present agenda guide future studies. We identified different in taxonomic groups, levels biological organisation, geographic regions. suggest focusing on global- landscape-scale processes, functional approaches, genetic molecular levels, eco-evolutionary dynamics as key avenues predict for human societies.

Current water quality guidelines across North America and Europe do not protect lakes from salinization

Proceedings of the National Academy of Sciences, Journal Year: 2022, Volume and Issue: 119(9)

Published: Feb. 22, 2022

Significance The salinity of freshwater ecosystems is increasing worldwide. Given that most organisms have no recent evolutionary history with high salinity, we expect them to a low tolerance elevated caused by road deicing salts, agricultural practices, mining operations, and climate change. Leveraging the results from network experiments conducted across North America Europe, showed salt pollution triggers massive loss important zooplankton taxa, which led increased phytoplankton biomass at many study sites. We conclude current water quality guidelines established governments in Europe do not adequately protect lake food webs, indicating an immediate need establish where they exist reassess existing guidelines.

Can machine learning accelerate process understanding and decision‐relevant predictions of river water quality?

Hydrological Processes, Journal Year: 2022, Volume and Issue: 36(4)

Published: March 29, 2022

Abstract The global decline of water quality in rivers and streams has resulted a pressing need to design new watershed management strategies. Water can be affected by multiple stressors including population growth, land use change, warming, extreme events, with repercussions on human ecosystem health. A scientific understanding factors affecting riverine predictions at local regional scales, sub‐daily decadal timescales are needed for optimal watersheds river basins. Here, we discuss how machine learning (ML) enable development more accurate, computationally tractable, scalable models analysis quality. We review relevant state‐of‐the art applications ML opportunities improve the emerging computational mathematical methods model selection, hyperparameter optimization, incorporating process knowledge into models, improving explainablity, uncertainty quantification, model‐data integration. then present considerations using address problems given their scale complexity, available data resources, stakeholder needs. When combined decades understanding, interdisciplinary advances knowledge‐guided ML, information theory, integration, analytics help fundamental science questions decision‐relevant

Practical Guide to Measuring Wetland Carbon Pools and Fluxes

Wetlands, Journal Year: 2023, Volume and Issue: 43(8)

Published: Nov. 28, 2023

Abstract Wetlands cover a small portion of the world, but have disproportionate influence on global carbon (C) sequestration, dioxide and methane emissions, aquatic C fluxes. However, underlying biogeochemical processes that affect wetland pools fluxes are complex dynamic, making measurements challenging. Over decades research, many observational, experimental, analytical approaches been developed to understand quantify C. Sampling range in their representation from short long timeframes local landscape spatial scales. This review summarizes common cutting-edge methodological for quantifying We first define each major provide rationale importance dynamics. For approach, we clarify what component is measured its temporal representativeness constraints. describe practical considerations such as where when an approach typically used, who can conduct (expertise, training requirements), how conducted, including equipment complexity costs. Finally, key covariates ancillary enhance interpretation findings facilitate model development. The protocols measure soil, water, vegetation, gases also relevant related disciplines ecology. Improved quality consistency data collection reporting across studies will help reduce uncertainties develop management strategies use wetlands nature-based climate solutions.

Abstract Both natural and anthropogenic processes can lead to the increasing salinity of surface waters. The knowledge about ecological consequences salinization on biota is limited especially in case microbiota, like diatoms.
